2 Answers

Panasonic pt-51hx41 i recently had the color chips replaced but now after 3 months on the left side of the screen i have a green line. from top to bottom going across the screen about 3 inches of the screen at that side everything is outta wack i tried to fix it using the remote but the green line seems like it is at the end but i can move it to the right of the screen no problem but wont go left any further, when the repair guy was over he had a hidden screen pop up with about 100 little boxes is that the way i can fix it or is the color chip shot again, also if possible can i use the hidden screen, and how do i get to it the repair guy would not tell me or show me that

I usually tell people at the outset that if they get into their service convergence menu and mess it up i wont be able to figure out what they did and you dont wanna do a scratch convergence to this chassis install new stk packs and the associated supply resistors cant miss em three 10 ohm 1/8 watt in parallel justt had one that i had replaced only of the two packs with a higher current stk pack ie; stk 392 -120 150 etc the resistors were subbed with a single flameproof 2.2 ohm 1/2 watt the service menu on that product is an art not easily mastered and am assuming that your skill set is not capable of even attempting any of this pay someone about 400 bucks for inhome call or go down to wally world and shop for a new crt projo tv i think the economics of it will quickly become apparent

I suspect that you have several capacitors in the convergence circuit that have gone out of tolerance if this problem did not show up until several months after the repairman left. These parts usually have to be unsoldered, tested for capacitance and equivalent series resistance (ESR's) and replaced one at a time. It is very unlikely you'll be able to adjust it out. If the set is over 7 years old, I would consider replacing it with a HDTV set. Otherwise, it could run about $400 to repair I would guess.
